Seven-String Surgery

by Robbie O’Brien with Antonio Tessarin

The 7-string guitar is a very popular instrument in Brazil. It is used as an accompaniment instrument for a style of music known as chorinho. However, many classical players also find themselves migrating to the 7-string instruments. So, what do you do if you currently have a 6-string instrument but desire the broader range of possibilities that a 7-string instrument can offer? You take your guitar to Brazilian luthier Antonio Tessarin and let him work his magic.

Antonio taught me guitar building years ago when I lived in Brazil and we often exchange pictures and information about projects that are on our benches. The following pictures were recently sent to me by Antonio. They show the process of him converting one of his 6-string guitars into a 7-string guitar. With his permission I am sharing them with the Guild of American Luthiers so that others may benefit. Warning: Contains graphic images that may not be for the faint of heart!
